STOVE-PIPE FASTENER.

SPECIFICATION forming part of Letters Patent No. 236,921, dated January25, 1881.

Application filed May 8, 1880. (Model.)

To all 'whom 'it may concern:

Be it known that I, ALBERT TRoLLoPE, of Detroit, in the county of Wayneand State of Michigan, have invented a new and useful Improvement inStove-Pipe Fasteners, of which the following is a specification.

My invention has for its object the secure andelose fastening ofstove-pipes to their wallholes, thereby securing a certain and safeconnection and avoiding all danger from their falling, and, by closingall unnecessary opening, improving the draft.

The invention consists of a circular metallic wall-plate with a circularopening in its cenis attached, by bolts and nuts, an adjustable metallicband of the same shape and size as the flan ge, and in alike position asto the other halfof the opening. It is by means of this band, whenfastened in its place, that the pipe is rmly secured to the plate andchimney hole. T-wo iron straps fastened opposite to each other on theinside rim of the plate extend inwardly, so that when the plate isagainst the wall their ends reach into the flue of the chimney. On theends of those straps are adjustable p ieces of L shape, secured bybolts, in the cross-limb of which are thumbscrews, which, when adjusted,press against the side of the iiue, and thus draw the plate closely andsecurely to the wall. An outside metallic covering, Whose cross-sectionmay be of ogee or any suitable shape, is fastened by lugs which enterand are pressed into wedgeshaped recesses in the plate, and is designedto give a suitable finish to the improvement.

In the drawings, similar letters indicate like parts.

Figure lis a perspective view ofthe device with the outside coveringoff. Fig. 2 is a horizontal cross-section, showing the device attachedto the chimney.

In the drawings, A A represent the wallplate; B, the flange around halfthe opening; G, the adjustable flange, which is secured to the flange Bby the bolts c a', which pass through suitable pieces' 0r flanges, b b cc', at

5othe ends of the iiange B and band C. This devices, constitute a clampby which the stovepipe is firmly held in position. From the outsidecenter of the band C projects a piece or lug, b, which plays looselyinside a couple of small prongs or hooks Which rise from the plate, theobject being to keep the band in its place near the plate. D D aremetallic straps fastened to the plate A A by the nuts e e', to the endsof which straps are attached the adjustable L-shaped pieces E E, bybolts through the slots ff', near the ends of the straps, and by reasonof which they may be lengthened or shortened to suit the varyingthickness of chimneys. Through the end of the adjustable angularextensions E E are set-screws h h', pointing inwardly toward the plate,and which, screwed in place, press against the side of the chimney-Hue FF, and thereby draw the wall- `plate AA close and securely against thewall.

G represents a rose-plate, which is attached to the wall-plate by meansof the lugs z' i, which project inwardly from the rim, and which aremade to enter and fasten into the wedgeshaped recesses K K', which areformed for that purpose on the Wall-plate. The projections m m aresimplyintended for rests for the rose-plate when in place.

The method of fastening the device to the wall and to the pipe issimple,`and it is easily done. The bolt which'fastens oneof the strapsto the plate is iirst loosened, so that it may have play enough to enterthe chimney-hole. When the plate is against the wall, see whether theadjustable angular extensions E E are of the right length 5 if not,adjust them, put device back in place, and tighten the boltwhich securesthe strap. The adjusters arm may then be placed in through thepipe-hole, and the set or thumb screws screwed up until they press rmlyagainst the wall. The pipe is then put in place, the rose-plate Gbeingrst slipped over it, and the adjustable band bolted firmly down inplace around the pipe, which is thus securely and rightly fastened. Therose-plate is then slipped to its place and turned till securelyfastened.

What I claim as my invention is- 1. In a stove-pipe fastener, thecombination, with a wall-plate having a pipe-opening, one portion ofwhich is provided with an outwardly-projecting ange, ot' an independentband ICQ which extends about the remaining portion of the opening, andscrew-bolts which connect both extremities of said harige, respectively,with the corresponding extremities of' said band, substantially as setforth.

2. In a stove-pipe fastener, the combination, with a wallplate havingone portion of its pipe-opening provided with an outwardly-projectingange, of a band which extendsabout the unanged portion ot the opening,and screw-bolts which connect together corresponding ends of the flangeand band, said band being provided with a ing which engages with twoprongs projecting from the wall-plate, substantially as set forth.

3. In a stovepipe fastener, the combination, with a plate adapted to titagainst the wall, and a clamp extending in outward projection about thepipe-opening, of a roseplate which covers said clamp and wall-plate, andfastening devices which detachably secure the roseplate to theWall-plate, substantially as set forth.

4. In a stove-pipe fastener, the combination, witha plate adapted to fitagainst the wall, and a clamp which extends in outward projection aboutthe pipe-opening, of a rose-plate which covers the clamp and wall plate,said roseplate having its rim provided with inwardlyprojecting lugs,which pass through recesses formed in the wall-plate and engage with therear side of thelatter, substantially as set forth.

5. In a stove-pipe fastener, the combination, with a wall-plate providedwith metallic straps adapted to tit within the due, of angularextensions secured to the inner extremities of said straps, and screwssupported by said extensions and adapted to have end bearing against theinner side of the chimney-wall, substantially as set forth.

6. In a stove-pipe fastener,the combination, with a wall'plate providedwith metallic straps which extend within the ue, of angular extensionssecured in longitudinal adjustment to the inner extremities of thestraps, and screws supported in said angular extensions and adapted tohave end bearing against the inner side of the chimney-wall,substantially as set forth.

In testimony whereoflsign this specification in the presence of twowitnesses.

ALBERT TROLLOPE.
